Undefined symbol for architecture “_OBJC_CLASS_$_AFHTTPClient”

问题

Iam using cocoapods with AFNetwork. When I compile the followig error appears:

Undefined symbols for architecture i386:

  "_OBJC_CLASS_$_AFHTTPClient", referenced from:

It happens for the cocoapod classes either with 64 bits or 32. Tried solutions from here:

AFNetworking Library failing in iOS 7

And here:

Undefined symbols for architecture arm64

but they don't work, am I missing something?

I included the project, but do I have to link it in some other way?

回答1:

The problem arises because there is a syntax issue with a deprecation on the source files of JSONKIT, the auto fix apparently prevents the class from being accessed as mentioned here https://stackoverflow.com/a/14191829/2394901. This is in turn is because the pod file specifies:

pod 'AFNetworking', '~> 1.2'

I removed the pod (see How to remove CocoaPods from a project?) and then reinstalled:

$ pod install

With:

pod "AFNetworking", "~> 2.0"
